transfer cylinders which receive the impres-.'

sions from the form cylinders and transfer such impressions to a webpassing between the transfer cylinders, each transfer cylinder beingadapted to act as the impression cylinder for the other transfercylinder. It is one of the objects of my invention to provide a new andimproved form and arrangement of parts by means of which the transfercylinders may be moved in opposite .di-

rections away from. each other and out of contact with the formcylinders. It is another object of my invention to provide means wherebyat the same time the inking mechanisms may be thrown out of contact withthe form cylinders, such action being preferably brought aboutautomatically. It is another object of my invention to provide means ofthis type adapted to permit the inking mechanisms to be thrown againinto contact with the form cylinders or to be thrown still further outof contact with the form cylinders without any change in the position ofthe transfer cylinders. It is another object of my invention to providemeans of this type which shall serve, upon a further movement of theinking mechanisms away from the form cylinders after they have beenmoved out of contact with the form cylinders, to move the watermechanisms at the same time out of contact with the form cylinders. Itis another object of my invention to provide automatically-acting meansfor throwing. the inking mecha nisms out of operation when the transfercylinders are moved out of contact with the form cylinders. It isanother object of my invention to improve planographic printing machinesin sundry details hereinafter pointed out.

Fig. 8 is a diagrammatic view showing a modification by which the meansfor controlling the inking mechanism and the water mechanism for oneform cylinder are actuated in unison with the means for controlling theinking mechanism and the water mechanism for the other form cylinder.

Referring to Figs. 1 to 7 in which corresponding parts are indicated bythe same reference characters,-

1 15 indicates the framework of a printing machine provided with formcylinders 1'6-17 adapted to .carry 'planographic" printing facings ofany suitable type. Transfer cylinders 18-19 are movably mounted so as tobe movable into and out of contact with each other and into out ofcontact with the form cylinders 16-17. Each of the cylinders 18-19 isrevolubly mounted by means of a shaft 20 which has an eccentric mountingin heads 21 which are revolubly mounted in slide-blocks 22 which areslidably mounted upon the frame 15. Each of the slide-blocks 22 isadjustable relative to a slide-block 23 by means of a screw-threadedpinor bolt 24. The head 21 is adjustable angularly relative to theslide-block 22 by means of adjusting screws 25-26 by an adjustment ofwhich a slight adjustment of the shaft 20 may be effected by reason ofthe eccentric ,mounting of the shaft 20 relative to the head 21. Y Thedownward movement of the slide-block 22 is resisted by means of springs27-28 interposed between suitable portions of the framework 15 and lugs29 carried by the slide-block 22, the springs being mounted upon rods 30which are slidable relative to the framework. Each of the slide-blocks23 is supported by means of a pair of togglearms 31-32, the toggle-arm32 for the slideblock 23 at each end of each cylinder 18 being fixedupon a shaft 33 whereby they are adapted to move in unison. The arms 32at each end of the press are connected together by means of anadjustable link 34 whereby the two sets of toggle-arms at each and, ofthe press are adapted to operate in unison.

Water mechanism is providedfor moistening the planographic printingsurfaces of the cylinders 16 and 17, being mounted upon arms 35-36carried by the frame 15. The water mechanism for each form cylindercomprises a framework 37 pivotally mounted by means of a shaft 38 uponthe arms 35-26. Each frame 37 carries a water receptacle 39 in which aroller 40-is revolubly mounted, an oscillating roller 41 being providedfor transferring the water from the roller 40 to a second roller 42 fromwhich the water is transferred by rollers 43-44 to the form cylinder.Any suitable means, asdesired, is employed for rotating the fountainroller 40 and for moving the oscillating roller 41 in proper timedrelation. By reason of each of the frames 37 being pivotally mountedrelative to its arm 35 or 36, the entire water device can be turnedabout such axis so as to carry the rollers 43-44 out of contact with theform cylinders 16-17.

The inking mechanism for each of the cylinders 16-17 comprises afountain 45 which a roller 46 is revolubly' mounted, be-

ing fixed upon a shaft 47. The shaft 47 is rotated by means of abell-crank lever 48 provided with a pawl 49 acting upon a ratchet-wheel50, the lever 48 being actuated by means of a link 51 reciproca'ted by adriven member 52. An oscillating r0ller53 is swung alternately intocontact with the fountain roller 46 and a roller 54 from which the inkso deposited upon the roller 54 is transferred to and spread upon acyline der 55 by means of a plurality of distributing rollers 56, thecylinder 55 being mounted by means of a shaft 57 framework 15.

The fountain rollers 46 areadapted to be thrown out of action by meansof shrouds 58 which are movable into'the path of the pawls 49 forholding the pawls out of contact with the ratchet-wheels 50. The shrouds58 are adjustable by means of arms 59 relative to pivotally mountedplates 60 which are connected by a series of links 61, 62 and 63 andinterposed bell-crank levers 64 and 65 with arms 66 depending from theshafts 33, the arrangement being such that when the shafts 33 are turnedin clockwise direction in Fig. 1, as hereinafter described,the-pivotally mounted plates 60 are turned in the direction to move theshrouds 58 into operative position for stopping the operation of thepawls 49.

The means for transferrin the ink from the ink cylinders 55 to the ormcylinders comprises frames 67 pivotally mounted upon the shafts 57 Eachof these frames carries a plurality of rollers 68 by which the ink istransferred to the form cylinders, such rollers being movable out ofcontact with the form cylinders upon the movement of the frames 67relative to each other in opposite directions about the shaft 57. Meansis provided for .moving the frames 67 about the shaft 57 comprising arms69 carried by said frames havlng operative engagement at their lowerends wlth suitable cam grooves in cams 70-71 revolubly mounted upon the,axis of the cylinders 16-17, respectlvely. The cams 70-71 are providedwith gears 72-73 revolubly therewith meshin with pinions 74-75,respectively, by WhICh'Sald cams are adapted to be ing links 76-77pivotally connected to the .frames 37 and provided with studs or rollers"78 engagin suitable cam. grooves in the said cams 70- .1. The samemovement of the cams 7 0-7 1 asthat which throws the rollers 68 out ofcontact with the cylinders 1-6.-17 serves alsoto throw the watermechanisms out of contact, as will be readily understood.

Means is provided for rotating the cams 7071 automatically for givingthe rollers 68 of the inking mechanisms their initial movement out ofcontact with the cylinders 16-17 upon the downward movement of thecylinders 18-19, as above described; ',This

arms of which are yieldingly held against upward movement by means ofsprings 87.

Figs. 4150 7 best show the action of the links 8182. In Fig. 4: the pin84 of the cam 71 is shown as having been drawn; downward by the shoulder88 of the liilk 82, bringing the shoulder 89 of said link past thehorizontally-extending arm of the bellcrank lever 86 permitting thespring} 85 to draw the link 82 toward the right. In this position of thecam the rollers 68of the.

inking mechanism have been. moved'a short distance out of contact withthe form' oylinder, but the water mechanism remains still in contactwith the form cylinder by reason of a dwell in that portion of the canslot through which the roller 78 has moved during such initial rotationof the cam 71. Fig. 6 shows the link 8-2 in the same position as in Fig.4, but with the cam 71 rotated inanually in counterclockwise directionso as to bring the rollers 68 of the inking mechanism again into contactwith the form cylinder. Fig. 5 shows thecam 71 rotated manually inclockwise direction as compared to the showing in 4 for throwing therollers 68 farther out of contact with the form cylinder and forthrowingthe water mechanism also out of contact with the cylinder: Fig.

7 shows the position of the link 82 when the cam 71 is in the sameposition as that shown may be thrown out of-conta'ct with'th'e cylinders16-17 byhand when the links 81-,82 stand in either of their adjustedpositions. When the inking mechanism has been thrown out of contactautomatically, it may be either thrown farther out of contact ymanually-operated means or may be thrown back into contact.

Fig. 8 shows a modified form of construction in which the cams and 71are connected by a link 90 whereby they are adapted to operate inunison. g

The means for driving the presscomprises a motor 91 connected by meansof a suitable chain of gearing with the various driven parts of thepress. The toggle arms 31-'32 are operated by an auxiliary motor 92which is provided with a worm 93 meshing with a worm-gear A roller 95connected with the toggle-arms 3l32 engages a suitable grooved cam 96which is adapted to be rotated by connection with the gear 94. The motor92 is provided with a controller system so arranged that upon thestoppage of the motor 91 the motor 92 is thrown into operation in adirection to rotate the grooved cam 96 in counterclockwise direction inFig. 1 thereby moving the arms 3132 to the right in said figure andmoving the transfer cylinders 18-19 out of contact as above described.-By the rotation of the shafts 33 thus effected the inking rollers aremoved out of contact with the form cylinders, and the inking mechanismis thrown out of operation in the manner above described.

Means is provided for automatically throwing the motor 92 into operationfor withdrawing the cylinders 1819 from contact with each other and fromcontact with the form cylinders whenever at any time the web 97 breaks,the roller 98 is adapted to move downward causing an arm 99 to moveupward into contact with a pin 100 by which a controller circuit 101 isclosed serving to throw the motor 92 into operation. The controllermeans for the motor 92 is such that the motor can be thrown intooperation manually in either direction as' desired independently of themotor 91 and can likewise be thrown out of operation .independently, butis adapted to be automatically thrown into operation upon the stoppageof the motor 91 as above described, this being effected by any suitablemeans, not shown.

As is well understood by those; familiar with the operation of pressesof this type, whenever the operation of the press is stopped, even for ashort time, it is desirable to move the inking rollers 68 out of contactwith the form cylinders and to move the transfer cylinders out ofcontact with the form cylinders and out of contact with each other. Aswill be understood from the description given above, this result isattained automatically whenever the press is brought to a stop. In casethe operation of the press is to be stopped only temporarily, it issometimes desirable that the form cylinders be kept in motion with theinking mechanisms still in operative position with relation thereto soas to keep the designs on the form cylinders in proper condition. Thisresult is attained as above explained by moving the inking mechanismsback into operative position by hand through the medium of the p-inions7475 following the automatic action upon the inking mechanisms incidentto the stoppage of the press, the press being then started up again withthe transfer cylinders out of operative position. Inasmuch as the gearsby which the form cylinders and the transfer cylinders are operativelyconnected are maintained in mesh even when the cylinders themselves aremoved to the limit of their movement out of contact with each other, thedriving of the form cylinders as above set forth results in acorresponding driving of the transfer cylinders, but this isunobjectionable inasmuch as the transfer cylinders are out of contactwith the form cylinders. Whenever it is again desired to operate thepress for printing purposes after such a temporary stop, the cylinders181 9 can be brought to operative position through the medium of themotor 92 which may be started manually for this purpose.
